The first range of PMT products will offer a nominal output voltage of 12V with a wide operating temperature range from -10 C to +70 C and can withstand shock and vibration requirements (in accordance to IEC 60068-2-27 and IEC 60068-2-6 respectively). In addition to features like overvoltage and overload protections, Delta s PMT series of panel mount power supplies is unlike many other brands in the same price level. The PMT series is designed for cost competitive markets without compromising the quality of the components and product specifications. The series of products has an expected life time of 10 years and will have no output power de-rating from 90Vac to 264Vac. This versatile series has three different connector options (Terminal Block, Front Face and Harness) and can also be converted into L Frame (PML) or Open Frame (PMB) type of power supplies to satisfy different application needs.

Engineering Data De-rating Note Fig. 1 De-rating for Vertical and Horizontal Mounting Orientation > 50 C de-rate power by 2.5% / C 1. Power supply components may degrade, or be damaged, when the power supply is continuously used outside the shaded region, refer to the graph shown in Fig. 1. 2. If the output capacity is not reduced when the surrounding air temperature >50 C, the device will run into Over Temperature Protection. When activated, the output voltage will go into bouncing mode and will recover when the surrounding air temperature is lowered or the load is reduced as far as necessary to keep the device in working condition. 3. In order for the device to function in the manner intended, it is also necessary to keep a safety distance of 20mm with adjacent units while the device is in operation. 4. Depending on the surrounding air temperature and output load delivered by the power supply, the device can be very hot! 5. If the device has to be mounted in any other orientation, please do not hesitate to contact info@deltapsu.com for more details. Output De-rating VS. Input Voltage No output power de-rating for the input voltage from 90Vac to 264Vac 7
Assembly & Installation A B C Mounting holes for power supply (device). The power supply shall be mounted on minimum 2 mounting holes using M3 screw minimum 5mm length. This surface belongs to customer s end system or panel where the power supply is mounted. Connector Side Mounting (Vertical) Base Mounting (Vertical) Side Mounting (Horizontal) Fig. 2 Recommended Mounting Orientations PM -12V35W1AA / PM -12V35W1AG: Use flexible cable (stranded or solid) of AWG No. 22-12. User should calculate and select the suitable wire specification (type/quantity/diameter) according to actual output current. The torque at the Connector shall not exceed 13Kgf.cm. The insulation stripping length should not exceed 0.275 or 7mm (Refer to Fig. 3). PM -12V35W1AH: Use flexible cable (stranded or solid) of AWG No. 22-18. Please refer to Table 1 for the recommended Housing and Terminal. Table 1 Connector (Board Mounting) Housing Terminal Input (JST) B3P5-VH(LF)(SN) VHR-5N Output (JST) B2P3-VH(LF)(SN) VHR-3N SVH-21T-P1.1 Safety Distance D1 = 4.0mm Min. D2 = 6.0 mm Min. (For PMB Series) Fig. 3 Assembly Reference Ensure the mounted device is kept at 4mm safety distance at all sides from other components and equipments. In addition, to ensure sufficient convection cooling, always maintain a distance of 20mm from ventilated surfaces while the device is in operation. 8
For PMT and PML Series (Refer to Fig. 4): Only use M3 screw 3mm through the base mounting holes. This is to keep a safe distance between the screw and internal components. Recommended mounting tightening torque: 4~7Kgf.cm. For PMB Series: (Refer to Fig. 3): The mounting holes on any mounting accessories for the device should be kept at a diameter of < 6.5mm. This is to ensure sufficient safety distance between the mounting screw and the components around the mounting holes on the PCBA. Therefore, the diameter of the mounting screw should be kept at < 6.5mm. Fig. 4 Mounting Screw Safety Instructions If user s mounting orientation is not according to the recommended mounting orientations, please consult Delta for further information. L frame (PML) and Open frame (PMB) options are to be manufactured by Delta and not to be reconfigured by users from the standard enclosed configuration. The device is not recommended to be placed on low thermal conductive surface. For example, plastics. The enclosure of the device can become very hot depending on the ambient temperature and load of the power supply. Do not touch the device while it is in operation or immediately after power is turned OFF. Risk of burning! Do not touch the terminals while power is being supplied. Risk of electric shock. Prevent any foreign metal, particles or conductors from entering the device through the openings during installation. It may cause electric shock, safety hazard, fire and/or product failure. The power supply must be mounted by metal screws onto a grounded metal surface. It is highly recommended that the Earth terminal on the connector be connected to the grounded surface. Warning (For Standard Terminal Block and Front Face Terminal Block products): When connecting the device, secure Earth connection before connecting L and N. When disconnecting the device, remove L and N connections before removing the Earth connection. Accessories L-01: Latch P-03: Bracket These accessories are used to mount the panel mount power supply onto a DIN rail. 9
Functions Start-up Time The time required for the output voltage to reach 90% of its set value, after the input voltage is applied. Rise Time The time required for the output voltage to change from 10% to 90% of its set value. Hold-up Time Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time required for the output to reach 95% of its set value, after the input voltage is removed. Graph illustrating the Start-up Time, Rise Time, and Hold-up Time Inrush Current Inrush current is the peak, instantaneous, input current measured and, occurs when the input voltage is first applied. For AC input voltages, the maximum peak value of inrush current will occur during the first half cycle of the applied AC voltage. This peak value decreases exponentially during subsequent cycles of AC voltage. Dynamic Response The power supply output voltage will remains within ±5% of its steady state value, when subjected to a dynamic load from 0 to 100% of its rated current. 10
Overload & Overcurrent Protections The power supply s Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current exceeds 120% of I O (Max load). In such occurrence, the V O will start to droop and once the power supply has reached its maximum power limit, the protection is activated and the power supply will go into Hiccup mode (Auto-Recovery). The power supply will recover once the fault condition of the OLP and OCP is removed and I O is back within the specifications. Overvoltage Protection The power supply s overvoltage circuit will be activated when its internal feedback circuit fails. The output voltage shall not exceed its specifications defined on Page 3 under Protections. Additionally, if the I O is <120% but >100% for a prolong period of time (depending on the load), the Over Temperature Protection (OTP) will be activated due to high temperature on critical components. The power supply will then go into Hiccup mode until the fault is removed. Over Temperature Protection As mentioned above, the power supply also has Over Temperature Protection (OTP). In the event of a higher operating temperature at 100% load, the power supply will run into OTP when the operating temperature is beyond what is recommended in the de-rating graph. When activated, the output voltage will go into bouncing mode until the temperature drops to its normal operating temperature as recommended in the de-rating graph. Short Circuit Protection The power supply s output OLP/OCP function also provides protection against short circuits. When a short circuit is applied, the output current will operate in Hiccup mode, as shown in the illustration in the OLP/OCP section on this page. The power supply will return to normal operation after the short circuit is removed. Others Delta RoHS Compliant Restriction of the usage of hazardous substances The European directive 2011/65/EU limits the maximum impurity level of homogeneous materials such as lead, mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical and electronic equipment. RoHS is the abbreviation for Restriction of the use of certain hazardous substances in electrical and electronic equipment. This product conforms to this standard. 11
